Casio Men's G-SHOCK Oasis of Day and Night GA-2100AS-5AJF Watch

Product Highlights
From G-SHOCK, the brand that continues to pursue toughness and evolution, comes the OASIS OF DAY AND NIGHT series, inspired by the enchanting oasis where the summer sun shines brightly. This series features two models: the slim octagonal bezel GA-2100 and the rugged and robust GA-110. The OASIS OF DAY AND NIGHT series adopts a design theme of oasis in the day and night, with a skeleton dial that shines like a reflective water surface and a vapor-deposited index. The sand beige-based model represents the daytime oasis, while the dark gray-based model embodies the nighttime oasis, with varying shades of blue and green on the dials. Imagining the oasis that awaits at the end of an adventure, these season colors are perfect for marine sports and street fashion, offering a casual and easy-to-style look.
